Thisv` inventionl relates` tol a4 picker stickl and mounting thereforand.'` moreY particularly to a picker` stick. which` may beiv made4 from:metal and thelike. p v v Among they iactorstwhich: haveV impeded theadoption: of metal. picker'sticks are;, the: liability of injury to theloom.. mechanism-f.shouldthe picker stick encounter an obstructionkduring its .movement under the.- iniiuenceA of; the: powerstrap ol` theloom, andv the-` liability of the metal. to crystallize under theeffects of thershock caused bythe'sha-rp and rapid. impacts! to `whichpicker sticks; arefsubjected when inservice.

The primary objectif ott this'. invention. is to protect they mechanismof.. a. loorn: from injury should a pickerv stick thereof meet.. arrobstruction. dur.- ing.;` itsmovementl to and fro` in.. the: shuttle:box of. the'loom.

Another important;` object is toirendenfeasible the use of. metal pickersticks: in loomsandi to remove as far asl possible. at` least one-` of:the. major factors which produce crystallization in. such sticks.

The; above:` andother;` objectsmay be attained by employing this`invention which; embodies amongv its features." a-v laterally extending.stud mounted on a. loom. parallel,v alpickeir` stick. having a notch-lopening, through. one e'dgef near' its lower end: for: receiving.' the;lstud4 and;A pivotalfly supporting theipicker stick on. saidzparallel andmeans: on the'picker.` stick closing: the; open: end of. the notch and`movable automatically out ot notch closingspositionuwhenthelnormalmovement. of the picker stickis. obstructed..

Other features.includefaryoke. pivotally mounted on the picker sticknear the notch, a shoe carriedby theyoke'andmovable therewith into andout of notch closing positiomand yielding means connected tothe yokeVand tothe picker stick to hold.- theshoe in notch. closingl position.

Still other features include. ay cylindrical cushion mounted on the studfor rotation about the axis thereof, a picker stick" having a notchopening` through one edgev adjacent the. lower end thereof, said notchreceiving` the stud. rockably to support. the, picker stick` on the loomparallel and means on the picker stick closing the open end of the notchand movable automatically of the notch closing position when the normalmovement of the picker stick is ob structed.

Referring tothe drawings in, detaiLa picker stick. designated generallylIll comprisesA an elongated body l2' equipped atits upper endlwithconventional means for supporting a loom picker. Thepickerfstickisenlarged as` at' i4 adjacent its lowerA end, andentering theedge-.ofthe body |l2I directlyopposite the enlargement I 4 is a not-ch it; for."the reception. of.A the mounting. stud about which the pickerstickpivots. The body I 2 of the picker stick Ulis` preferably cast ofalight metalsuch as aluminum', magnesium or thef like; and is equippedvwith conventional power strap attaching; means` t8 and returnv strapattaching means 2l)y by which the.1 picker, stick is rocked about theaxis of its pivot.

Mounted on, tlfie` conventional rocker shaftfof the loom-'is a loomparallel` designated. generally 221Which is providedwith a horizontallyextend;- ing arm 24: having an elongated.longitudinal,y slot Zlformedtherein for the reception of theo-mounting stud 28 of the picker stick.This. mounting stud is held in various adjusted: positions. in` the slot26 by meansv of a conventional clamnnut 30; andfextends perpendicular.from the armv .'lllalong ai substantially horizontal axis.V Surrounding.the stud 28 is'a' bearing sleeve 32,.and encircling the bearing sleeveis a cylindrical cushion 34E which is preferably formed of rubber.' or.'other" suitable yielding. material. The cushion 34 is'4 held in placebetween the head of the stud 28,' and the arm: 242,, and. formsY theVsurface which contacts thetwallsf ofthez notch I6;- pivotally to supportthet pickerfstick one` the stud; The cushion 341 is preferablysubstantially equal: in` diameter'to the widtha` of' they notcl'fr. lt.. so: as to'. form. a snug' fit be.- tween:v the parts for the*purpose: of: accurately supportingV the: picker. stick in position. on`the loom` In order releasably to secure the picker stick I0 in place onthe cushioned stud 28 I provide a retaining member or yoke designatedgenerally 36 which comprises substantially U-shaped arms 38 which arepivotally supported as at 40 on the picker stick through hole 4| on theyoke directly above the axis of the inner end of the recess or notch IB.The arms 38 of the yoke 36 embrace the picker stick as will be readilyunderstood upon reference to the drawings, and provided at the ends thearms remote from the bight portion of the yoke are downwardly extendinghooks 42 carrying a curved shoe 44 which, as illustrated in Figure 4. isadapted to enter the slot or notch I6 3 to bear against the cushion 34and hold the picker stick on the stud 28. One end of a retractile coilspring 46 is coupled to the bight portion of the yoke 36 through hole5I, while its opposite end is adjustably connected as at 48 to a bracket50 carried by the body I2 of the picker stick I0 in upwardly spacedrelation to the enlarged portion I4 of the picker stick. The spring 46serves to retain the shoe 44 in contact with the cushion end of thenotch I6 before any damage can be .v

done to the loom. The opening of the notch will cause the picker stickto fulcrum about the obstruction at its upper end, and throw its lowerend off of the stud by moving the stud through the end of the notch I6,as suggested in Figure 2. By thus disconnecting the picker stick fromits normal pivot, it will be obvious that danger of injury to the loomwill be avoided. At the same time, when the trouble has been corrected,the picker stick may be remounted on the stud simply by causing the studto be received in the slot or notch I6 while the shoe 44 is held out ofslot closing position against the influence of the spring 46. As soon asthe spring 46 is released, however, it will be obvious that the shoewill swing downwardly under the eiort of the spring to close the end ofthe slot and hence restore the parts to working order.

Obviously, the restoration of the loom to a production basis requiresbut a few minutes, as no adjustment of the pivot of the picker stickneeds to be made. Obviously, the picker stick may be restored to itspivotal support with but a minimum of effort.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that minor changesin the details of construction and arrangement of parts may be resortedto without departing from the spirit and scope of the in- 4 positionwhen the normal movement of the picker stick is obstructed.

2. A picker stick and mounting therefor comprising a laterally extendingstud mounted on a loom parallel, a picker stick having a notch openingthrough one edge near its lower end for receiving the stud and pivotallysupporting the picker stick on said parallel, a yoke pivotally mountedon the picker stick near the notch, a shoe carried by the yoke andmovable therewith into and out of notch closing position and yieldingmeans connected to the yoke and to the picker stick to hold the shoe innotch closing position.

3. A picker stick and mounting therefor comprising a laterally extendingstud mounted on a. loom parallel, a cylindrical cushion mounted on saidstud for rotation about the axis thereof, a picker stick having a notchopening through one edge adjacent its lower end, said notch receivingthe stud rockably to support the picker stick on the loom parallel andmeans on the picker stick closing the open end of the notch and movableautomatically out of notch closing position when the normal movement ofthe picker stick is obstructed.

4. A picker stick and mounting therefor comprising a laterally extendingstud mounted on a loom parallel, a cylindrical cushion mounted on saidstud for rotation about the axis thereof, a picker stick having a notchopening through one edge adjacent its lower end, said notch receivingthe stud rockably to support the picker stick on the loom parallel, ayoke mounted on the picker stick to move into and out of position toclose the open end of the notch and yielding means to hold the yoke innotch closing position.

5. A picker stick and mounting therefor comprising a laterally extendingstud mounted on a loom parallel, a cylindrical cushion mounted on saidstud for rotation about the axis thereof, a picker stick having a notchopening through one edge adjacent its lower end, said notch receivingthe stud rockably to support the picker stick on the loom parallel, ayoke pivotally mounted on the picker stick near the notch, a shoecarried by the yoke and movable therewith into and out of notch closingposition and yielding means connected to the yoke and to the pickerstick to hold the shoe in notch closing position.
